....I was talking with Klaiber and he thought it would be good to see the Gotha or the HP escorted all the way across the map. Not exactly bombing London but something similar. This sets up the Strategic Target objective. The objective is a building set way, way behind enemy lines. It can only be done by the plane labeled "Strategic Bomber". It will take at least one hour to get there. The target is randomly selected. It is a distinct building easily identified. Only 2 AAA trucks defending but still, best bombed from altitude for safety. The challenge is to get to the target. Too simple? Too easy? Too easy to stop? What, another bomber mission? Can't we come up with something more imaginative that does not involve bombs? Well, not really.
You haven't provided any incentive for that mission to actually be escorted, which I think might have been an integral part of the original concept. If the only part of that mission that you offer points for is to bomb something, folks are going to assign resources based only on the scoring of those points (note the comments made already about using stealth as the main challenge, implying no escort). Perhaps if you make the successful RTB of the bomber after successfully destroying the target the points-scoring object of that mission, it might encourage the actual escorting of the bomber more than otherwise. Another possibility could be to have an assigned escort of one of more scouts, designated in the mission for that express purpose, to have to make it to the target and back, and THEY (one or more?) have to RTB successfully to score points.
Escorting is a very hard task to be successful at and this type of mission might be a good way to try to encourage that. The points gained could be more than the usual amount if it turns out to be excessively difficult.
One inherent problem that I see though is the fact that the Gotha can climb so much higher than the HP, which no matter how you look at it gives it a far greater range of altitudes to hide at.
If you assign this type of mission to only one side, it would be equally difficult for both teams to accomplish, because both teams must do the exact same mission with the exact same planes (within a side-changing phase); could be either side's bombers, in fact could be rotated from one side to the other in different phases of an event. In other words, in one phase both sides have a chance to do it in HP's; in the next phase both have to attempt it in the Gotha.
It might be worthy to consider that those actual extreme long-range missions in WWI were done unescorted by scouts; essentially, the Gothas in their group were their own escorts. I'm not sure to what extent HP's that were sent deep into enemy territory in daylight had escort either....maybe some DH4's were there for part of the ride, or not. I think in both cases though, "interceptors" that were sent up to challenge these formations were not just patrols that happened to be up there flying around. Spotters at some point visually located the bomber formation and then interceptors were launched to attempt to destroy some or all of it. Could this be a part of the mission? A message informing a nearby drome of enemy altitude and heading?
